What if there is no network to send text messages by mobile phone?

1. According to the information you provided, if your mobile phone can't connect to the Internet normally, please check the following:

1. If you don't restart your phone after upgrading to the 4G package, you can't use the Internet function normally;

2. Confirm whether there is a network. I suggest you use it in a place with strong signal.

3. Check whether there is any phone bill in the account. If the balance is insufficient, it needs to be recharged before it can be used;

4. Confirm whether the parameters of the mobile phone have been set;

5. Check whether the USIM card is inserted. If it's plugged in and still doesn't work, I suggest you go to the business hall to check whether the USIM card is faulty or not.

6. Check whether there is anything wrong with the mobile phone. It is recommended that you change the machine for testing.

7. If your mobile Internet access reaches its peak in the current month, the system will automatically turn off your data functions such as Internet access, MMS and mobile newspaper, and turn them on automatically next month.

The above situation has not been solved, you can contact the local manual customer service for handling.

2. If the mobile phone can't send SMS, you can try to restart or change the mobile phone test, and check the following reasons:

1. SMS center number is not set correctly. Please re-enter the correct SMS center number (+861301012500 or 0086 130 165438).

2. No signal or low battery;

3. Because the system is busy during the holiday short message sending peak period, it is suggested that you try again later or avoid the sending peak period;

4. The sending format is incorrect. If you send a short message to PHS users, you need to add the area code before the number;

5. The short message sending time exceeds 24 hours;

6. The mobile phone shields the short message sending function;

7. Blacklisted by SMS;

8. Insufficient quantity balance;

9. SMS inbox and outbox are full.

If the above reasons cannot be solved, you can contact the local manual customer service or go to the business hall to confirm whether the SMS function is enabled and hand it over to the staff.
